  • Day — 7 Challenge ends

New problem statements will be published every 48 hours, and yes, ace coders will win amazing vouchers.

This is a rated contest.

As usual, there will be some nice prizes for the top three competitors:

  • First place: $100 Amazon gift card.

    I am not sure what you mean by "you and noobita." However, since noobita redirects to my account, I am compelled to clarify that I have NOTHING to do with this contest. In particular, I am not responsible for any and all mental damages incurred by solving problems set by RestingRajarshi.

Arpa Have you ever wrote validators for problem in Hackerearth? Test data for "Separating Numbers" is wrong. For last 10 tests the following condition is not holding: "in each query we are told to destroy a previously undestroyed edge".

In Hackerearth, from contest to contest so many problems are badly tested, start I start thinking that problems are not tested at all. Am I right? If so, what's your role of tester?

    Forget about testing, I don't even think any effort is put into problem setting. As an example, consider this problem which was asked in the previous Hackerearth Circuit : Link.

    There are two really big issues with the problem.
    1) This has been directly taken out of a book, and I can even guess that the question was even the same.
    2) Implementing the exact pseudo code in the picture will give full score !!! (I mean wtf!)

      Whaaaat? I understand that one may put extremely easy problem to encourage newbie participants, but putting the problem along with it's solution is something new and one more time prove that admins and tester of Hackerearth are not interesting in increasing their's contests quality.

      But I must mention, that at least author's and tester's solution compiles successfully :) (when I participated last time, this was not the case, they just submit some code, which doesn't even compile).

        Previously, it was risky to reject problems because we hadn't enough problems in our queue. Now I'm rejecting more problems these days, our queue is almost full for the next 4~5 months, and it opens up my hands to improve the quality of problems.

        So, I hope that next contests, you enjoy more.

      Note that our Circuit contests are almost educational and the problem is very easy.

        It's all the more reason why such problems shouldn't be given in educational contests, unless ofc you are "educating" them how to write actual code from pseudo code itself! If that's the case, then I don't have any issues.
        Even a beginner will first try to implement the given code out of curiosity and submit it, even if he can't analyze the complexity.

      I originally proposed this problem with large restrictions, but it was decided to make the restrictions smaller.

    You are right. Unfortunately, setter missed writing validator and I didn't realize it. But almost always we have validators.

    I test problems and we had a jump in the quality of contests. Back to 6 months ago, there was a worse situation. I'm trying to improve. I'm seeking experience. Thanks for your feedback. Be sure that I'm trying to become better and better.

    Arpa is there for the money money money and testing is his least concern.

When will the test cases for "Separating Numbers" be fixed?
